Abstract
A method for determining a flow distribution in a formation having a wellbore formed therein comprises the steps of positioning a bottomhole assembly in a wellbore, the assembly including an injection port for dispensing a fluid, a first sensor disposed upwell from the injection port, and a second sensor disposed downwell from the injection port, wherein each of the sensors generates a feedback signal representing a flow rate of the fluid in a portion of the wellbore, determining an approximate depth of a portion of the bottomhole assembly in the wellbore, generating a data model based upon an instruction set, the data model representing flow characteristics of the fluid in the wellbore, wherein the data model is derived from the feedback signal and the approximate depth of the injection port, and analyzing the data model based upon an instruction set to extrapolate a characteristic of the formation.
